Hi,

I hope you have GRUB loader.

Please find below link for UBUNTU docs

https://help.ubuntu.com/community/GrubHowto?highlight=%28grub%29

You can find any docs on UBUNTU site

(in grub config file (/boot/grub/menu.lst or some like this) all you don't wanna see must with # symbol in front of line)

sudo apt-get autoremove

should do the job.
The command will remove the other Kernel from the boot Menu and the probably still installed old Kernel. You should do this everytime the system upgrade installs a new Kernel. You probably will recognize this if there's a second kernel in the boot menu again after an upgrade

when i typed the command "sudo apt-get autoremovce" and got this message:

I think it only means that my kernel didn't upgrade or something. when I went to the grub folder and checked the menu.lst like "radist" told me about I got this:

seems to me that I have another kernel added: version 2.6.20-16 or something. well the problem began when i typed the command "sudo gdm" or something. as a beginner for linux I tend to play around a little bit. i was trying to install/run the fluxbox at that time and it was saying that i should run it in the gdm. so I typed that command just to guess. my compute gave me a blue screen error like in windows and it saying about server x. I can't really restore my system so I manually turn it off. and when I rebooted that's when got the 2 options.

hello again. it seems to me that I fixed the problem. I found out that those options are actually version of kernels. if you want to remove one of them from the boot options you just need to remove it by using the Synaptics package manager. just leave the kernel header installed though. you might get problems like "no sound" if you uninstalled all the package.

thanks for your help though. the information you gave me will help me in the future...
